Wow. Sorry to say it, but you're definitely better off without him. Plenty of women use men's deodorant. I do (and shower gel and shaving cream) because I'm allergic to most of the floral esters used to scent women's products. It's also less likely to contain antiperspirants which bother a lot of people.

He got issues smh

Why would anyone keep deodorant just in case for their affairs anyway...?

Did you also tell him that you're gay and pregnant?

Boyfriend smells girlfriends armpit Boyfriend "You've been sleeping with Jeffrey haven't you!?! I can smell his scent on you!" Girlfriend "It's just my deodorant......" Boyfriend "bah, what do I look like an idiot?" Girlfriend "yep, a single one"

My condolences OP this situation you got put in over someone else's ignorance sucks, my gf used to borrow my deodorant for the exact same reasons many people here already mentioned (stronger, usually has antiperspirants, etc) but it's just unfortunate this had to happen to you.

How did Sherlock Holmes miss that there was no women’s deodorant there? It may hurt now, but it’s better he is gone. You would have had stupid children with him.

Put a ladies deodorant in his bathroom and accuse him back.

I use men’s deodorant for the same reason. Sounds like you are better off without him. He would just find other reasons why he thinks you are cheating.
